A 47-year old man with progressive dysphagia had an exophytic mass lesion in the distal esophagus, which on biopsy was confirmed to be an adenocarcinoma. Panels A and B: Endoscopic ultrasonography (EUS) with the radial scanning probe demonstrated transmural invasion (T3), regional lymphadenopathy (LN), and a right pleural effusion. Panels C and D: The electronic linear scanning probe also demonstrated a T3N1 tumor with perigastric lymphadenopathy. EUS fine needle aspiration demonstrated metastatic adenocarcinoma. Note that the needle traverses normal gastric wall uninvolved with tumor.
